Application Note: Signal to Noise Ratio Calculator

10 July 2011

This white paper describes the Signal to Noise Ratio Calculator from Photometrics. Enter the dark current value for your camera, the exposure time of image to calculate the number of electrons in your signal, noise caused by dark current, total noises, signal:noise (SNR) and noise in grey scale values (ADU's). By using these measurements, you can ensure that your image acquisitions are at an acceptable SNR, allowing for cleaner, crisper images.
